Fortune said Apple was the most admired company, topping the list for the seventh year in a row, with not only USD 171 billion in revenues in financial year 2013 but also tremendous interest among fans and the market about its next big product.

"Bets are on a smartwatch or AppleTV, but the company is also reportedly turning its attention to cars and medical devices," Fortune said.

PepsiCo led by India-born CEO Indra Nooyi was on the 42nd spot while Ajay Banga-led Mastercard is also on the list but not in the top 50.
